The question, in short
From a grid diagram with points A and B marked, find the coordinates of A and calculate the gradient of line AB.
Summarised in our own words. Use the official paper for the exact wording and the diagram.
Part (a) · 1 mark
Write down the coordinates of point A from the diagram.
- 1A is 4 units left and 3 units up
- 2A = (−4, 3)
Answer(−4, 3)
Part (b) · 2 marks
Work out the gradient of the line AB.
- 1A = (−4, 3), B = (4, −1)
- 2Gradient = (−1 − 3) ÷ (4 − (−4))
- 3= −4/8 = −1/2
Answer−1/2
